Recommended Practices

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities.

Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.

Locate control system networks and remote devices behind firewalls and isolating them from business networks.

When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices.

CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.

CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.

CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.

Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.

Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.

CISA also recommends users take the following measures to protect themselves from social engineering attacks:

Do not click web links or open attachments in unsolicited email messages.

Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.

Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.

No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time.

What Our Clients Say

“This system allowed me to identify missing components when the model validation engine ran. These were components which had infrequent changes and therefore were not commonly documented. The ASSURANT™ model told us that there were some elements missing. When we compared our sources against the model result, we discovered existing legacy components which had previously lacked documentation. The addition of these components to the model has given us confidence in the model’s completeness and improved our cyber readiness.”

Cyber Model Engineer

“Without the ASSURANT™ attack path analysis visual capability, it’s difficult to explain the complexities of a cyber battlespace to non-experts, and us good guys in the fight are often only learning from our mistakes in the wake of a cyber-attack. The different ways to visualize attack paths allows time to get ahead of the tactics and techniques of cyber actors by allowing us to simulate “black hat” scenarios for when a network artifact becomes compromised.”
